BACKGROUND Insertion of an implantable left ventricular assist device (LVAD) complicated by early right ventricular (RV) failure has a poor prognosis and is largely unpredictable. Prediction of RV failure after LVAD placement would lead to more precise patient selection and optimal device selection. METHODS AND RESULTS We reviewed data from 245 patients(More)
OBJECTIVES Techniques employed today concomitantly with left-sided heart valve surgery address secondary tricuspid valve regurgitation at 3 anatomic levels-annulus, commissure, and leaflet-although success of these alone or in combination in eliminating tricuspid regurgitation is uncertain. Our objective was to assess the comparative effectiveness of these(More)
OBJECTIVES The purpose of the present study is to report the five-year follow-up results of the ERACI II trial. BACKGROUND Immediate and one-year follow-up results of the ERACI II study showed a prognosis advantage of percutaneous coronary intervention (PCI) with stents over coronary artery bypass grafting (CABG). METHODS A total of 450 patients were(More)
OBJECTIVE To compare hospital outcomes of on-pump and off-pump coronary artery bypass surgery. METHODS From 1997 to 2000, primary coronary artery bypass grafting was performed in 481 patients off pump and in 3231 patients on pump. Hospital outcomes were compared between propensity-matched pairs of 406 on-pump and 406 off-pump patients. The 2 groups were(More)
UNLABELLED Specialized Conducting Cells in Human PV. INTRODUCTION Depolarizations similar to those from the sinus node have been documented from the pulmonary veins after isolation procedures. We assessed the hypothesis that sinus node-like tissue is present in the pulmonary veins of humans. METHODS AND RESULTS Pulmonary vein tissue was obtained from(More)
OBJECTIVES To examine the clinical profiles, operative outcomes, and late results of patients with pseudoaneurysm of the thoracic aorta. METHODS From 1990 to 2002, 60 patients underwent repair of aortic pseudoaneurysm: ascending aorta in 70%, ascending aorta and arch in 15%, descending aorta in 10%, and arch alone in 5%. Mean age was 53 +/- 15 years, and(More)
BACKGROUND Accurate prediction of cardiac surgery-associated acute kidney injury (AKI) would improve clinical decision making and facilitate timely diagnosis and treatment. The aim of the study was to develop predictive models for cardiac surgery-associated AKI using presurgical and combined pre- and intrasurgical variables. STUDY DESIGN Prospective(More)
OBJECTIVES The Cox maze procedure is the gold standard for ablation of atrial fibrillation in patients undergoing mitral valve surgery, and new approaches to atrial fibrillation ablation must be compared with it. Therefore, we sought to determine the time-related prevalence of atrial fibrillation and its risk factors after combined Cox maze and mitral valve(More)
OBJECTIVE Less invasive approaches to mitral valve surgery are increasingly used for improved cosmesis; however, few studies have investigated their effect on outcome. We sought to compare these minimally invasive approaches fairly with conventional full sternotomy by using propensity-matching methods. METHODS From January 1995 to January 2004, 2124(More)
